Hello, Michel and all,
I'm now working on prediction for the Perseids 2008 (with an overview for
2009). I can say that in 2008 Perseids backgound could be a little
stronger than usual (maybe up to 110-120 meteors on ZHR scale instead
of 100). I also found an encounter with 4 rev. trail, described by Esko
Lyytinen, but can't still give any details on it.
Best regards, Mikhail
MV> Hi folks,
MV> As known the evolution of the Perseid meteoroid stream is dominated by the influence of planetary perturbations witch translates in a variable maximum activity. On August 11, 2004 we witnessed
MV> the effect from Jupiter on the stream with a small burst of faint meteors. I haven't seen the 1993 outburst because we were clouded out in Belgium (in one single hole I saw precise one bright
MV> Perseid ;-) but I have seen a tremendous August 11-12 in 2004 with a single burst of earth grazing Perseids around peak time and a spectacular display of bright meteors and higher numbers in
MV> the second part of that night ('the filament'). I counted at best 134 Perseids in one hour! My question now is this: there was a close approach between the shower and Saturn in 2006. We may see
MV> some effects on the stream between 2008-2010: possibly richer than the 2004 return. OK: as the predictions of Maslov tells us on his website: 2009 will be the most interesting year (bad
MV> moonlight). In my archive (pr
MV> eparing for the 2008 Perseids) a found a formal message on meteorobs (27088) from Esko Lyytinen (27088) and I read about a possible interesting encounter with the 4REV (?) trail. Is this
MV> still a valuable fact or is this prediction changed after the 2004-05 events?
MV> Thank you for responding,
MV> Michel.
